Siemens Logo Eplan P8 Macrol May 2026

EPLAN P8 is a parts-oriented, object-based system. Without a macro, every time you insert a LOGO! 8.3 (e.g., 6ED1052-1MD08-0BA1), you must manually draw the power supply connections, the input circuits (I1 to I8, I9 to I16 for DM16 variants), the relay outputs, and the analog inputs.

By creating a Window Macro (EMA) or Symbol Macro (EMS), you achieve:

When you download or create a macro for the LOGO! 8 series, a professional macro includes the following layers:

This is where the real power lies. If you have a specific way you like to wire your LOGO! controllers (e.g., always wiring Emergency Stops to Input I1, or keeping spare outputs on specific terminals), you should build your own Window Macro. Siemens Logo Eplan P8 Macrol

Steps to create a Window Macro:

Now, for your next project, you simply insert that Window Macro. All the relative wire numbers and device tags will update automatically based on your page settings.

This article explains how to plan, document, and implement small automation projects using Siemens LOGO! controllers together with EPLAN Electric P8. It covers device selection, schematic creation, PLC I/O mapping, macro use, export/import options, and practical tips to streamline engineering and reduce errors.

In the world of modern industrial automation, efficiency is measured not just by programmable logic controller (PLC) cycle times, but by the speed of engineering design. For small-scale automation projects, the Siemens LOGO! series (Smart Relay/Logic Module) is a ubiquitous choice. However, integrating these devices into a complex electrical CAD environment like EPLAN P8 can be tedious.

Enter the Siemens Logo Eplan P8 Macrol (Macro). This combination transforms a repetitive, manual drafting task into a 30-second insertion process. But what exactly is an EPLAN macro for Siemens LOGO!, and how do you build a sustainable library?

This article dives deep into the creation, architecture, and best practices for LOGO! macros in EPLAN P8. Now, for your next project, you simply insert
